If the Executive is deemed on the date of termination to be a “specified employee” within the meaning of that term under Section 409A(a)(2)(B), then with regard to any payment or the provision of any benefit that is considered deferred compensation under Section 409A payable on account of a “separation from service,” such payment or benefit shall not be made or provided until the date which is the earlier of (i) the expiration of the six (6)-month period measured from the date of such “separation from service” of the Executive, and (ii) the date of the Executive’s death, to the extent required under Section 409A. Upon the expiration of the foregoing delay period, all payments and benefits delayed pursuant to this Section 6 (whether they would have otherwise been payable in a single sum or in installments in the absence of such delay) shall be paid or reimbursed to the Executive in a lump sum, and any remaining payments and benefits due under this Agreement shall be paid or provided in accordance with the normal payment dates specified for them herein. With respect to expenses eligible for reimbursement under the terms of this Agreement: (i) the amount of such expenses eligible for reimbursement in any taxable year shall not affect the expenses eligible for reimbursement in another taxable year; and (ii) any reimbursements of such expenses shall be made no later than the end of the calendar year following the calendar year in which the related expenses were incurred, except, in each case, to the extent that the right to reimbursement does not provide for a “deferral of compensation” within the meaning of Section 409A of the Code.

7. Representations. Executive represents and warrants to the Company that (a) the execution, delivery and perfom1ance of this Agreement by Executive does not and will not conflict with, breach, violate or cause a default under any contract, agreement, instrument, order, judgment or decree to which Executive is a party or by which Executive is bound, (b) Executive is not a party to or bound by any employment agreement, noncompetition agreement or confidentiality agreement with any other person or entity (other than any such agreement with any subsidiary or predecessor of the Company) and (c) upon the execution and delivery of this Agreement by the Company, this Agreement shall be the valid and binding obligation of Executive, enforceable in accordance with its terms.

8. Survival. Executive acknowledges and agrees that Sections 5-10 of this Agreement shall survive the separation of Executive’s employment for any reason.

9. Severability. The Parties intend for this Agreement to be enforced as written. However, if any section or portion of a section of this Agreement shall to any extent be declared illegal or unenforceable by a duly authorized court having jurisdiction, (a) then the remainder of this Agreement, or the application of such section or portion of such section in circumstances other than those as to which it is so declared illegal or unenforceable, shall not be affected thereby, and each section or portion of such section of this Agreement shall be valid and enforceable to the fullest extent permitted by law; and/or (b) because of the scope of a section or portion of such section is found to be unreasonable, the Company and Executive agree that the court making such determination shall have the power to “blue-pencil” the Agreement as necessary to make it reasonable in scope; and in its reduced or blue-penciled form such section or portion of such section shall then be enforceable and shall be enforced.
